ChemSheet的靈活性和實用性相結合的電子表格應用程序與嚴格的,多階段熱力學計算。 每個應用程序被定義為一個獨立的工作表在Excel «,其中整個模擬可以做到的。

輸入和輸出的電子表格模型是聯繫在一起的ChemApp熱力學編程庫。 重複複雜的熱力學計算為一個多樣化的應用範圍無論在化學和冶金因此啟用直接從電子表格。 這兩種反應動力學和傳熱可以採取帳戶與RATEMIX ® -算法。 因此,ChemSheet是一個工具,感興趣的專業人士在處理工業和冶金,以及那些與地球化學和環境科學。

在世界範圍內,熱力學方案ChemSage和SOLGASMIX可用於許多數以百計的大學和研發實驗室獲得的結果可靠,快速和高效。 現在ChemSheet帶來的權力,這些行之有效的熱化學計劃進入到每個人,誰是熟悉Excel的電子表格。

 簡單易學,易於使用的分析工具

所有這一切都需要的是一台PC與Windows 95/98/NT和Excel的電子表格程序。 有了這個,你可以收回你的投資在ChemSheet並在適當的熱化學數據分鐘。 您可以使用強大的計算能力的ChemSheet調查範圍廣泛的技術問題,節省工時比傳統模擬方案。

  • 分析過程的可行性進行實驗前
  • 設計你的過程和數量計算的結果-無論是化學或精力充沛
  • 把你的團隊決策過程中的必需品時,改變或改善
  • 選擇你的最佳工藝條件,如:pH值,氧化還原,溫度,壓力,分壓等
  • 減少的數目實驗
  • 分析試驗工廠或處理數據
  • 增加產量從提取或回收進程
  • 痕量雜質的形態,或在此過程中排放
  • 避免安全或環境問題

 化學計算的新時代的不斷發展

ChemSheet是直接後裔廣泛使用的SOLGASMIX和ChemSage吉布斯能源minimiser方案,發展25年前開始古納爾埃里克森博士。 這兩個方案具有最大的頻率帶的技術文獻。 ChemSheet,界面的熱化學計算工作已發展到在Excel™電子表格。 模擬多階段過程化學與傳熱傳質反應動力學模型或突出的也包括在內。

在Excel中的計算模型™可以建立一個用戶友好的ChemSheet對話菜單,也可以是定制的用戶誰不太熟悉的熱力學原則。 因此ChemSheet提供了一個複雜的過程嚴謹的方法在化學熱力學的研究,以及開發工具,任何專業工作與實際工程和設計。

 User-Friendly simulation saves time and money
ChemSheet combines the flexibility and practicality of spreadsheet applications with rigorous, multi-phase thermodynamic calculations. Each application is defined as an independent worksheet in Excel«, in which the entire simulation can be done.

The input and output of the spreadsheet model are linked to the ChemApp thermodynamic programming library. Repetitive complex thermodynamic calculations for a diverse range of applications both in chemistry and metallurgy are thus enabled directly from the spreadsheet. Both reaction kinetics and heat transfer can be taken account with the RATEMIX®-algorithm. Therefore, ChemSheet is a tool of interest to professionals in process industries and metallurgy, as well as to those working with geochemistry and environmental sciences.

Worldwide, the thermodynamic programs ChemSage and SOLGASMIX are used in many hundreds of universities and R&D laboratories to obtain results reliably, quickly and efficiently. Now ChemSheet brings the power of these well-established thermochemical programs into the reach of everybody, who is familiar with Excel-spreadsheets.

The input fields are given as ‘Equilibrium Conditions’ and ‘Incoming Amounts’ (lower left). The collection table of results (above) and the respective Excel-chart are also shown.


 Easy to learn, easy to use analytical tool

All that is needed is a PC with Windows 95/98/NT and the Excel-spreadsheet program. Having this, you can recover your investment in ChemSheet and in the appropriate thermochemical data in minutes. You may use the powerful calculation capabilities of ChemSheet to investigate a wide range of technical problems and save hours of work when compared to conventional simulation programs.

  • Analyse the feasibility of a process before conducting the experiments
  • Design your process and calculate the results in quantity - whether chemical or energetic
  • Focus your team on essentials when making process changes or improvements
  • Choose your optimum process conditions, e.g.: pH, redox, temperature, pressure, partial pressure etc.
  • Reduce the number of experiments
  • Analyse pilot plant or process data
  • Increase yields from extraction or recycling processes
  • Trace the speciation of impurities or emissions in the process
  • Avoid safety or environmental problems

Figure 3. The options for a ChemSheet calculation may be given directly in the worksheet or via a dialog window with control lists for phases and constituents derived from the thermodynamic data-source.


 New era of chemical calculations from continuous development

ChemSheet is a direct descendant of the widely used SOLGASMIX and ChemSage Gibbs energy minimiser programs, the development of which began 25 years ago by Dr. Gunnar Eriksson. These two programs have the greatest frequency of quotation in the technical literature. In ChemSheet, the interface of the thermochemical calculation has been developed to work in Excel™ spreadsheets. Simulation of multi-stage process chemistry with heat and mass transfer models or salient reaction kinetics has also been included.

The computational model in Excel™ can be built with a user-friendly ChemSheet dialog menu, or it can be custom-made for users who are less familiar with thermodynamic principles. Thus ChemSheet provides a rigorous method for complex process chemistry in thermodynamic research, as well as a development tool for any professional working with practical engineering and design.

With the on-line combination of the Excel-spreadsheet and the Gibbs energy minimisation the chart becomes updated simultaneously with the calculation. The dialog window for hydrogen input is also shown.
